Development of statistics analysis method for coal gasification performance prediction
Tokyo Electric Power Company (TEPCO) and Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI) established the statistical analysis method, which predict the performance for coal gasification. This method is based on the test results and coal analysis data of the Coal Gasification Test facility (the authors call CGT plant, capacity of 6 tons/day dry coal base and TEXACO type gasifier). The authors carried out the test using 15 kinds of coal and over 7,500 hours of test runs. From these tests, they have conformed the gasification performance data for these coals, which have wide varying characteristics. In addition, they have confirmed stable and high efficiency operation. Also, they are trying the scale up study using 1,000 tons/day demonstration plant (Cool Water Program) gasification performance data. Using this method, the authors can estimate gasification performance for a commercial size TEXACO type gasifier. For process design and development of the integrated coal gasification combined cycle, gasification performance data are very important. Therefore, the coal gasification performance data for each coal is needed. Many types of methods for gasification performance simulation for using chemical equation and heat material balance are proposed. The statistics analysis method does not need the complex chemical equation and heat material balance calculation. The authors purport they can calculate the performance very easily and quickly in the power plant in the near future.
